Hannah’s allergies and Scooter's cold lead the group to a discussion of health and ways to keep healthy. Barney shows everyone how healthy foods, exercise, and even laughter can improve and maintain your health. "Dr. Barney" gives the children pretend check-ups. Through the Adventure Screen, the children learn not to fear x-rays, and are motivated to make their own pretend x-rays using chalk on black paper. Meanwhile, Barney is trying to recall where he's misplaced an x-ray of himself that he'd like to show his friends. Hannah finds the x-ray and the children see that Barney is "all heart" and a true "picture of health!"
